I would like to know how to bill immunochemistry code 88342 and 88341 on a case that have multiple specimen. for the 88342 code there is an MUE that says you can only bill 3 per date of service. additional stains done on the same specimen will be bill with an 88341 per instruction. My concern is if I have a case that have 10 specimen, I know that I can bill (3) what code will I use to bill the additional 7 specimens? Please I need some clarification. if you have any written rules or tell me where I can find it. I would appreciate very much.
